COOLER TEMPERATURES WILL LINGER THROUGH SATURDAY BEFORE A STRONGER WEATHER SYSTEM MOVES IN ON SUNDAY. && .UPDATE...MADE A MINOR UPDATE TO THE FORECAST TO INCREASE SOME CLOUD COVER OVER MUCH OF THE AREA FOR THE REMAINDER OF THE MORNING AND LESS SO FOR THE AFTERNOON HOURS. WE ARE CURRENTLY FORECASTING 101 FOR A HIGH TEMPERATURE IN LAS VEGAS...AT MCCARRAN...WHICH WILL TIE THE DAILY RECORD SET IN 1978. WILL BE ASSESSING THE NEED FOR SOME WIND ADVISORIES ACROSS PORTIONS OF THE AREA FOR TOMORROW... PARTICULARLY IN NYE AND ESMERALDA COUNTIES. && .PREV DISCUSSION...315 AM PDT WED SEP 30 2015 .SHORT TERM...THROUGH FRIDAY NIGHT. ONE MORE VERY WARM DAY IN STORE FOR THE REGION BEFORE A MUCH DESERVED COOL DOWN BEGINS ON THURSDAY. HIGH TEMPERATURES ACROSS THE REGION TODAY WILL RANGE FROM 6 TO 12 DEGREES ABOVE AVERAGE WITH THE GREATEST ANOMALIES ACROSS THE SOUTHERN AND EASTERN PORTIONS OF THE FORECAST AREA. THE FINAL 100 DEGREE DAY OF THE YEAR FOR LAS VEGAS IS A GOOD BET TODAY ASSUMING WE REACH THE CENTURY MARK. ON THURSDAY...A COLD FRONT WILL CUT INTO THE REGION AS A TROUGH OF LOW PRESSURE IS KICKED INTO THE GREAT BASIN AND DRAGS A SOUTHWARD ADVANCING FRONT WITH IT. THIS WILL USHER IN SOME COOLER AIR TO THE REGION AS IT INVADES THE AREA FROM NORTHWEST TO SOUTHEAST. TEMPERATURES WILL REMAIN ABOVE NORMAL AHEAD OF THE FRONT THURSDAY BUT SHOULD DROP A FEW DEGREES FROM WEDNESDAYS NUMBERS THANKS TO DECREASING HEIGHTS ASSOCIATED WITH THE TROUGH MOVING IN. GUSTY WINDS CAN BE EXPECTED AREA WIDE AHEAD OF THE FRONT...ESPECIALLY ACROSS THE WESTERN MOJAVE DESERT NORTHEASTWARD INTO LINCOLN COUNTY. WIND SPEEDS LOOK TO REMAIN BELOW ADVISORY LEVELS BUT SOME POCKETS OF STRONGER WINDS WILL BE POSSIBLE. IN ADDITION TO THE WIND...SOME SHOWER ACTIVITY WILL BREAK OUT AS THE FRONT MOVES THROUGH THE SIERRA AND SOUTHERN GREAT BASIN REGION. SOME INSTABILITY IS PRESENT IN THESE AREAS AS WELL AS STRONG FORCING SO WE MAY SEE SOME ISOLATED THUNDERSTORMS BREAK OUT. SHOWER ACTIVITY WILL PROGRESS QUICKLY EASTWARD THROUGH THE DAY ALONG THE FRONT AND DIMINISH BY LATE THURSDAY EVENING. GUSTY NORTHWEST WINDS WILL FOLLOW THE FRONTAL PASSAGE THURSDAY NIGHT INTO FRIDAY MORNING. CONDITIONS ON FRIDAY WILL BE CONSIDERABLY COOLER BUT STILL ONLY NEAR SEASONAL NORMAL. BREEZY NORTH WINDS CAN BE EXPECTED MUCH OF THE DAY BUT OTHERWISE FAIR WEATHER IS EXPECTED. .LONG TERM...SATURDAY THROUGH WEDNESDAY. CONFIDENCE CONTINUES TO INCREASE IN A DEEP CLOSED LOW DIVING OUT OF WESTERN CANADA INTO CALIFORNIA AND NEVADA BY SUNDAY AS THE ECMWF REMAINS FAIRLY CONSISTENT WITH ITS PREVIOUS RUNS FROM THE PAST FEW DAYS. THE FORECAST WAS MORE HEAVILY WEIGHTED TOWARD THE ECMWF SOLUTION DUE TO ITS RUN-TO-RUN CONSISTENCY. MEANWHILE THE CANADIAN MODEL REMAINS QUITE CLOSE TO THE ECMWF TRACK AND TIMING WHILE THE OPERATIONAL GFS HAS BEEN THE OUTLIER AT LATCHING ON TO THIS SCENARIO. THE 00Z GFS DEPICTS THE CLOSED LOW STALLING OVER OREGON SUNDAY AND MONDAY THEN OPENING UP AND SWINGING ACROSS THE GREAT BASIN TUESDAY AND WEDNESDAY. SATURDAY WILL SEE THE FORECAST AREA UNDER A FAIR WEATHER PATTERN WITH WEST TO NORTHWEST FLOW ALOFT AHEAD OF THE CLOSED LOW DROPPING DOWN THROUGH THE PACIFIC NORTHWEST. TEMPERATURES WILL BE A LITTLE ABOVE NORMAL WITH NORTH BREEZES IN THE MORNING BECOMING LIGHT AND VARIABLE BY AFTERNOON. IF THE APPROACHING CLOSED LOW HOLDS TRUE TO THE ECMWF FORECAST...IT WILL BE ROLLING DOWN THROUGH CENTRAL CALIFORNIA BY 12Z SUNDAY WITH GUSTY SOUTH WINDS DEVELOPING OVER MUCH OF THE FORECAST AREA AHEAD OF IT. BY SUNDAY AFTERNOON...THE CENTER OF THE LOW WILL BE OVER THE SOUTHERN SIERRA WITH MUCH OF THE FORECAST AREA UNDER BROAD UPWARD FORCING AND SUFFICIENT MOISTURE ON THE EAST SIDE OF THE LOW LEADING TO A CHANCE OF SHOWERS OVER ZONES FROM LAS VEGAS NORTHWARD...AND MORE ESPECIALLY LINCOLN COUNTY. POPS WERE INCREASED INTO THE 15-30 PERCENT RANGE FOR THESE ZONES. THE SYSTEM IS THEN FORECAST TO PROGRESS ACROSS SOUTHERN NEVADA SUNDAY NIGHT AND LIFT INTO UTAH EARLY MONDAY WITH DIMINISHING CHANCES FOR SHOWERS FROM SOUTHWEST TO NORTHEAST MONDAY. TEMPERATURES WERE ALSO LOWERED BASED ON THE ECMWF GUIDANCE...BUT STILL NOT QUITE AS LOW AS THE ECMWF MOS VALUES. TUESDAY AND WEDNESDAY WOULD SEE A SLOW WARMING TREND UNDER DRY ZONAL FLOW BEHIND THE SYSTEM WITH TEMPERATURES SLIGHTLY BELOW NORMAL. && .AVIATION...FOR MCCARRAN...EAST-SOUTHEAST WIND COMPONENTS WILL BE AN ISSUE THIS AFTERNOON AND SPEEDS COULD EXCEED 10 KNOTS AT TIMES.
